The 5-day, 40-hour work week has been the American standard since 1940. But a growing number of companies β€” and even a few governments β€” are testing what happens when you cut it to 4 days. The results so far? Productivity stays the same or increases, employees are happier, and turnover drops dramatically.

The Evidence So Far

The world's largest 4-day work week trial ran in the UK in 2022 with 61 companies and 2,900 employees. The results were striking:

  • Revenue increased by an average of 1.4% during the trial
  • Employee burnout dropped 71%
  • Sick days decreased 65%
  • Resignations dropped 57%
  • 92% of companies continued the 4-day week after the trial ended

Similar trials in Iceland, Spain, Portugal, and Japan produced comparable results. The pattern is consistent: when people work fewer hours, they waste less time and focus more intensely during work hours.

Companies Already Doing It in America

A growing list of US companies have adopted permanent 4-day work weeks:

  • Kickstarter: Moved to a 4-day week in 2022. Productivity maintained.
  • Bolt (fintech): Permanent 4-day week since 2022. Employee satisfaction scores hit record highs.
  • Exos (performance coaching): 4-day week since 2022. Revenue growth continued.
  • Buffer: 4-day week since 2020. Reports no productivity loss.
  • Basecamp: 4-day weeks during summer (May-October) since 2008.

Most are tech companies and knowledge-work firms. But the concept is spreading to other industries.

Why It Works

The typical American office worker is only productive for 2 hours and 53 minutes out of an 8-hour day, according to a study by Vouchercloud. The rest is spent in unnecessary meetings, checking social media, chatting with coworkers, and context-switching.

A 4-day week forces companies to:

  • Eliminate unnecessary meetings (the #1 time waster in offices)
  • Set clearer priorities β€” with less time, only important work gets done
  • Give employees longer uninterrupted focus blocks
  • Replace vague "being busy" with measurable output

Which Industries Could Adopt It?

Most likely:

  • Tech and software companies
  • Marketing, design, and creative agencies
  • Professional services (accounting, consulting, law)
  • Government agencies (some European governments already have)

Most challenging:

  • Healthcare (hospitals need 24/7 staffing β€” but could rotate 4-day shifts)
  • Retail and hospitality (customer-facing, but could stagger schedules)
  • Manufacturing (depends on automation level and shift structure)
  • Education (school schedules are deeply embedded in society)

Will It Become Law?

California introduced a bill (AB 2932) to make 32 hours the standard work week for large employers, though it hasn't passed yet. At the federal level, Representative Mark Takano has introduced the 32-Hour Workweek Act multiple times.

Legislation is unlikely in the near term, but market forces may do the work instead. Companies offering 4-day weeks attract significantly more applicants. As the talent market tightens, more employers will adopt it as a competitive advantage.

How to Get a 4-Day Work Week

  • Propose a trial: Ask your manager for a 90-day pilot with measurable goals. Show the research.
  • Switch companies: Search for "4-day work week" on LinkedIn and Indeed. Filter by companies that offer it.
  • Go freelance: Freelancers and contractors set their own hours. Many already work 4-day weeks.
  • Negotiate compressed hours: Some companies allow four 10-hour days instead of five 8-hour days.
🎯 Key Takeaway: The 4-day work week isn't a fantasy β€” it's already working at hundreds of companies worldwide with proven results. Productivity stays flat or improves, employees are healthier, and companies save on overhead. While legislation is slow, market forces are accelerating adoption. If you want one, the fastest path is proposing a trial at your current company or switching to an employer that already offers it.
